天山南北麓广泛分布厚度不等的黄色粉砂堆积物,这些堆积物呈不连续的带状分布。另外在天山山区的河流阶地上也有零星分布。其颜色多为黄褐、土黄、褐红色;具层理,大部含有少量砾石;距地表一两米内孔隙较多,向下孔隙迅速减少。对于这些堆积物的成因众说纷云,但以风成论者为多。他们认为天山南北麓的黄色粉砂堆积物,是哈萨克斯坦

Tianshan Mountains are widely distributed between the north and the yellow thickness of yellow silt deposits, these deposits were discontinuous ribbon-shaped distribution. In addition, there are sporadic distributions of rivers in the Tianshan Mountains. Its color is mostly yellow brown, yellowish brown, reddish brown; with bedding, most of them contain a small amount of gravel; within a meter or two from the surface of the earth more pores down rapidly reduced. There are many reasons for the formation of these deposits, but many wind scholars. They think that the yellow silt deposits in the north-south Tianshan Mountains are Kazakhstan
